Diana will get buffed a tiny bit, but her Q will still deal a low amount of dmg.

Diana will get buffed as a jungler a bit, and that is the role where she is actually better after her last nerfs.
She is stronger than people think, cause they play her mid. In that lane she needed her Q dmg, what got nerfed.
In the jungle she needs the high R range and the W shield and dmg, what gets buffed back a bit.

Diana went from OP to trash... Riot needs to learn to nerf step by step.. maybe Morello is getting too old for the job

Trash?
Even pros consider Karma as a valid solo queue pick, but not for tournaments and she would be the trash champ No.1.

There is no real trash champ in solo queue, only some weaker and some stronger ones.

Diana is on the weaker side. But mainly cause people still play her as a jungler.
The 75 R range buff and 0-12 W dmg buff won't help her laning too much (or the 1 sec longer shield duration). But in the jungle, where she doesn't need the Q too much, but her passive and W.
Spirit of the spectra wraith gets buffed and is actually already one of the better items for her (when jungling).

Diana is still a good champ and if you like her it doesn't matter that she is a bit weaker than others for 1-2 weeks.
If you are searching for an offensive AP jungler, get her.
